Abstract

PURPOSE:To raise resistance to liquid leakage by the procedure in which groove is provided in the surface of one or both gaskets at the contact between gasket and cathodic can or anodic can and then the surface of the groove is coated with a sealant, e.g., asphalt, etc. CONSTITUTION:The anode 1 is inserted into the anodic can 6 and then the separator 4 is placed on the anode. Then, the sealant 9, e.g., asphalt, pitch, wax, synthetic rubber, synthetic resin paint, varnish, adhesive, etc., is coated on the surface of the gasket 5 provided with the ring groove 8 along its outside and inside circumferences, and then the cathodic can 7 is soon pushed into the gasket. Then, the cathode is filled in the can and the electrolyte 3 is injected into it. Then, the anodic an 6 and the cathodic can are combined and sealed. Thus, the groove 8 formed in the gasket 5 serves to prevent the break of the coat of the sealant 5 on the surface of the gasket due to compressive force exerted at the time of sealing.
